Abstract: A fuser member using an RFID tag and a method for evaluating the performance of a fuser member using a RFID tag are disclosed. An RFID tag may be attached to a fuser member during a manufacturing process. Production data pertaining to the fuser member may be stored on the RFID tag during the manufacturing process as well. Once manufactured, the fuser member may be used in a xerographic apparatus. Run-time data may be stored in the RFID tag during operating of the xerographic apparatus. After the fuser member is removed from the xerographic apparatus, the performance of the fuser member may be evaluated by examining the run-time data. The fuser member may include a core, optionally made of metal, an insulating layer, and an RFID tag.

Abstract: A plurality of scanner bars is arranged in precisely located holes in the frame of a media handling device to detect the passage of the lead and trail edge of media. The multiplicity of scanner bars, arranged linearly at a right angle to the direction of motion of the media, is sampled at some frequency. The scanner bars give not only arrival and departure time of the media from each scanner bar location, but also making some assumptions about the shape of the media, information about the orientation of the media relative to the direction of motion. This information can be used to diagnose improper media handling mechanisms upstream of the sensor or provide information to downstream corrective mechanisms. Preprinted test media, such as, ladder charts, etc., can be used to extract velocity profiles and other paper path dynamic characteristics.
